It is not by any means certain that a bonder will work. The certain way is to remove architraves, skirtings, electrical fittings etc and then nail galvanised expanded metal lathing (XML) all over the area tightly to the existing wall (say large headed galvanised nails at 12" centres both ways). When finished check that the XML is tight to the wall everywhere and put in extra nails if necessary. After that, proceed as normal but being attentive to pressing the plaster well into the XML.
I am 83 on 10 August next, sft42. I had 5 years in the womens army, followed by exactly 50 years in the international construction industry. I am still a long way from dead, and sometimes, particularly after half a bottle of Bell's, get an overwhelming urge for a pair of muddy wellies and a donkey jacket again.
you have to take the paint off, thats the best way, 98 percent is good enough, and if you are reskiming you can do it rough. I have a special tool for this work, looks like a spade but its a scraper, its muscular work and dusty so if you arent up for it I quite understand, find someone with a construction vacuume and nothing to do, good luck, and dont listen to the knowall who says you can just plaster over paint, Its very stupid, I know I did it., you could I suppose get a machine for that, what about a heat gun, and tou could also try wetting the wall, works on wall paper depending on the glue.but youd have to scratch it up a bit first, wet it up after the days scratching, what about a wood rasp, real big one, a saw held on the right angle can be good.
